An innovative approach to battery materials could bring sodium-ion energy density and charging speeds far closer to those of ...

Carbon nanotubes can open and close in response to acidity, guiding water and ions one by one and mimicking how natural cell ...

When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of ...

Plants fix 258 billion tons of CO2 in their chloroplasts through photosynthesis every year. For these cell organelles to work properly, they require certain minerals—particularly ions of the metals ...

Sodium-ion batteries are considered a promising and sustainable alternative to lithium-ion batteries. However, high storage losses during the first charging ...

The work, led by Chunsheng Wang at the University of Maryland, offers a relatively simple way to make lithium-ion batteries more durable using standard materials and ...

Water doesn’t behave the same way in a glass as it does as ice in your freezer. When water is heated to several thousand ...

New research shows that these fields speed up water dissociation not by lowering energy costs, but by increasing molecular disorder once ions form. The reaction becomes entropy-driven—exactly the ...

Rolling MXene sheets into scrolls at gram scale yields 33-fold conductivity gains and superconductivity at 5.2 K absent in ...

Researchers demonstrated a new method of cooling trapped ions using chip-based systems, which could enable more stable and scalable quantum computers and quantum sensors.

U.S. scientists used density functional theory to reveal how sodium ions are stored in nanoporous carbon anodes for sodium-ion batteries, identifying dual ionic and metallic storage mechanisms within ...

Dot and cross diagrams help us to model when ions are formed from atoms. Here’s an example using sodium and chlorine. They form ions which bond to form sodium chloride. 2. Work out how many electrons ...
